An Ultimate Guide to Duplex Steel Fasteners

About Duplex Steel Fasteners


We are a manufacturer and supplier of fasteners such as bolts, screws, stud bolts, threaded rods, nuts, washers, dowel pins, and other special bolting parts made from duplex 2205 grade, comparable to S32205. Duplex alloy S32205 fasteners are available in both metric and imperial sizes. In accordance with the most recent material specifications, duplex stainless steel 2205 fasteners are made from premium quality rolled bar stock or forged bars. We can produce alloy S32205 fasteners in accordance with worldwide dimension standards such as ASME, DIN, ISO, and others. Along with grades F60, UNS S31803, DIN EN 1.4462, and Uranus 45n, these duplex fasteners are also offered in these similar materials.


Bolts made of duplex steel UNS S32205 are one of the most sought-after goods in today's markets. These bolts are renowned for being efficient and effective. The strongest and most durable grade is believed to be duplex steel, UNS S32205. These fasteners are typically used in harsh environments with high temperatures.


Bolts made of duplex UNS S32205 can only be fixed if they undergo a complete annealing procedure, which is rarely used above 300 degrees Celsius. These UNS S32205 Bolts Suppliers, which cannot be further toughened by thermal treatment, must be heated to 1020°C to 1100°C and then swiftly cooled. Duplex UNS S32205 bolts have nearly twice the strength of austenitic stainless steel Type 304. Duplex UNS S32205 bolts are employed in a variety of applications because of their exceptional corrosion resistance and high strength.


Applications of Duplex Steel Fasteners


Fasteners made of duplex steel are made of extremely hard metals with a dual-phase microstructure. Austenite and ferrite are the two forms of steel that make up these fasteners. Excellent mechanical qualities like high yield strength, toughness, and stress corrosion cracking are produced by the combination of these two metals. Fasteners made of duplex steel are frequently used in several sectors, including desalination equipment, oil and gas, and chemical processing.


Fasteners manufactured of duplex steel are typically constructed of stainless steel for most purposes. They are not easily accessible off the shelf or via a distributor of stainless fasteners. It is crucial to get them from a specialized supplier to guarantee quality. They must have rolled threads and carefully managed heating to guarantee that they are of the highest caliber. Hex or round bar is used for CNC-machine duplex fasteners. For superior wear, resistance, and yield strength, consider forging heads over machined ones if at all possible.
